a The oxidation mechanism for ML under irradiation or exposure to OH radicals. b The simplified model mechanism for ML film oxidation. c Rate constants for the model fit. However, note that the model sensitivity to the values of the initiation rate constant can be very low. For example, in the dark indoor environment values of kinit from 10-20 to 10-7 s-1 fit the data well (see Supplementary Fig. 8). For this reason, we list upper limits to the values of kinit. The best fit rate constants (units of s-1) were 2.5 × 10-8, 9.4 × 10-9, and 8.2 × 10-11, for the dark indoor environment, OH oxidation, and irradiation experiments, respectively. These values were applied in Fig. 2c, d, and f.
